Shop parts for a 2019 Yamaha TTR110 Dirt Bike.

Regular oil changes are vital to keeping your 2019 Yamaha TTR110 running strong—ensuring long engine life, smooth power, and peace of mind out on the trail. This bike is a great machine for beginners and kids, and luckily, changing its oil is straightforward—even for first-time DIYers. Follow this robust, proprietary guide from MotoSport.com to make sure you get the job done right and efficiently.

Tools & Supplies You’ll Need

  • 12mm socket or wrench (for drain bolt)
  • Oil catch pan (any old pan, cut bucket or commercial plastic oil drain pan)
  • Clean funnel (to help pour in new oil)
  • Rags or shop towels
  • Measuring cup or marked oil bottle (for precise fill)
  • Fresh engine oil (Yamaha recommends 10W-40 Yamalube, but any quality motorcycle oil of this weight works; you’ll need about 28 fluid ounces/0.85 liters)
  • Gloves (optional, but recommended to keep your hands clean)

Important Model-Specific Notes for the 2019 TTR110

  • No oil filter on these bikes—this makes oil changes especially quick and simple.
  • The TTR110’s oil change procedure has remained the same since 2012, so this guide covers 2019 and other recent TTR110 models perfectly.
  • The engine holds 28 fluid ounces (0.85L) of oil. A quart of 10W-40 exceeds this, so you’ll have a bit left over.
  • Overfilling can cause performance issues, oil blow-by, leaks, or damage. Always check your dipstick after filling and adjust if needed.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Run your TTR110 for 5–10 minutes. This thins the oil, helps debris suspend, and makes draining much easier.
    • Turn the bike off and place it upright on a stand.
  2. Gather Tools and Prepare Work Area
    • Lay down rags around the drain area to catch any drips.
    • Place your oil catch pan beneath the oil drain bolt (found on the bottom left side of the engine).
  3. Remove the Oil Fill Cap
    • Unscrew the large oil fill/dipstick cap on the right engine case. This allows oil to flow out more smoothly.
  4. Drain the Old Oil
    • Using a 12mm wrench, carefully loosen and remove the drain bolt.
    • Let all oil drain out; gently lean the bike from side to side to ensure complete drainage.
    • Inspect the drain bolt and its crush washer. Replace the washer if it’s damaged to prevent leaks.
    • Wipe the bolt clean and reinstall by hand, then gently snug it with your wrench (do not overtighten).
  5. Add Fresh Oil
    • Place your funnel in the oil fill hole.
    • Pour in exactly 28 fluid ounces (0.85L) of 10W-40 oil.
    • If your oil bottle has quart and ounce markings, mark 4 ounces from the top and fill to that level. Alternatively, use a measuring cup.
  6. Check and Correct the Oil Level
    • Keep the bike level and upright (have a friend help if necessary).
    • Insert the dipstick, screw it down, then remove and check the oil level.
    • Oil should land between the marks—not over the upper mark.
    • If the level is low, add a small amount and recheck. If too high, carefully crack open the drain bolt and drain a little until correct.
  7. Start and Recheck
    • Start the engine and let it idle for a minute.
    • Shut off, let oil settle a couple minutes, then recheck the dipstick.
    • Top up if needed. Do not overfill.
  8. Dispose of Used Oil Properly
    • Pour your old oil into a suitable container and take it to a recycling center, auto parts store, or Yamaha dealer.
  9. Clean Up
    • Wipe down the engine area, tools, and your work space.

Pro Tips from MotoSport.com

  • Keep a maintenance log with date, hours/miles, and oil brand for easy tracking.
  • Always use high-quality motorcycle-specific oil for best clutch and engine protection.
  • If you ride in dusty conditions often, inspect and change the oil more frequently.
  • An oil change is a great time to check your air filter as well—it’s quickly accessible and critical for engine health.
